AGENTS.md: record delete_branch_on_merge + disabled Wiki/Projects settings

 - A repo commit-identity guard hook requires the git author email to match the personal class (`laksh.sadhwani07@gmail.com`) for this remote — set via local (not global) `git config user.email` if a commit is rejected.
 - Release packaging: `.github/workflows/ci.yml` (build/vet/test on PR and push to `master`), `.github/workflows/release.yml` (goreleaser on `v*` tag push), and `.goreleaser.yml` (darwin/linux amd64/arm64, publishing a Homebrew formula to `Laaaaksh/homebrew-writ` via `brews:`) mirror the sibling `Laaaaksh/vessel` repo's setup. Releasing requires a `HOMEBREW_TAP_TOKEN` repo secret — without it goreleaser falls back to `GITHUB_TOKEN`, which cannot write to the separate tap repo and the release fails (this is what broke vessel's first release). `.github/dependabot.yml` runs weekly `gomod` + `github-actions` version-update PRs on top of the GitHub-side Dependabot alerts/security-fixes toggles (those live in repo settings, not files); expect its PRs against `master`. `.github/workflows/codeql.yml` runs CodeQL code scanning (languages go,actions) on PRs, pushes to `master`, and a weekly cron — its status check is named `CodeQL`; activity is proven by `/code-scanning/analyses` entries, not default-setup state.
 - `go.mod`'s `go` directive is the single source of the Go toolchain for CI and releases: both workflows pass `go-version-file: go.mod` to actions/setup-go, so that line decides which compiler (and which stdlib security patches) ship inside released binaries — v0.2.x shipped go1.22.12, EOL since Feb 2025, before the directive was bumped to a supported line. Audit it against the two-current-versions support policy whenever cutting a release.
-- `master` is branch-protected: required `Test` status check (strict), enforced for admins, conversation resolution required, no direct pushes — land every change through a PR and wait for its `Test` check (`gh pr merge` honors the rules); `CONTRIBUTING.md` documents the contributor-facing flow.
+- `master` is branch-protected: required `Test` status check (strict), enforced for admins, conversation resolution required, no direct pushes — land every change through a PR and wait for its `Test` check (`gh pr merge` honors the rules); `CONTRIBUTING.md` documents the contributor-facing flow. Repo settings keep `delete_branch_on_merge` on: after any PR merges (including this run's own gnhf branch PRs), GitHub deletes that head branch from origin — re-push the local branch to recreate it; don't misread the vanished origin ref as data loss. Wiki/Projects tabs are deliberately disabled; don't re-enable them when auditing settings.
 - `cmd/writ/main.go`'s `version`, `commit`, and `date` must stay package-level `var`s (with `default*` const placeholders), never `const` — goreleaser's `-X main.version=...` ldflags silently no-op against a `const` string, so every released binary would misreport itself. `versionString` is the single place that renders them; it omits the `(commit ..., built ...)` suffix when both are still at their defaults.
 - `goreleaser check`/`release` (v2.16+) soft-deprecate the `brews:` key in favor of `homebrew_casks:`; kept `brews:` here to match vessel's existing convention and the tap's `bin.install`-style formula. `dist/` (goreleaser's output dir) is gitignored.
 - `brews:` sets `directory: Formula` so the generated formula writes to `Formula/writ.rb` in `Laaaaksh/homebrew-writ`, not the tap root. Homebrew resolves a tap's formulae from `Formula/` first, then `HomebrewFormula/`, then the root — a formula anywhere in `Formula/` always wins over one at the root, so omitting `directory` risks silently serving a stale root formula the moment anything else creates a `Formula/` dir in the tap (this happened to vessel's tap). Confirm the key name (`directory` vs the older `folder`) against the installed goreleaser's own schema (`goreleaser jsonschema`) before touching this, not from memory.
